[RESOLVED] problem with uploading image

andy_wang

hi, i created a very simply php page to try upload image, but the system keeps telling me i did not upload any image at all, the true is i did select a image file and pressed "upload" button. can anyone help, pls?

many thanks in advance

the page is named "ADupload.php"
here is the code:

if(isset($_POST['submit'])) 
{
  if(empty($_FILES['uploadfile']))
  {
    	echo "<script>history.back();alert('You did not upload a file!');</script>";
		exit;
  } 
  else 
  {
		$maxfilesize=10240;
		if ($_FILES['uploadfile']['size'] > $maxfilesize) 
		{
		  echo "<script>history.back();alert('file is too large!');</script>";
		  exit;
		} 
		else 
		{
			  if ($_FILES['uploadfile']['type'] != "image/gif" AND $_FILES['uploadfile']['type'] != "image/pjpeg") 
			  {
				echo "<script>history.back();alert('This file type is not allowed!');</script>";
				unlink($_FILES['uploadfile']['tmp_name']);
				exit;
			  } 
			  else 
			  {
			   move_uploaded_file($_FILES['uploadfile']['tmp_name'],"/ADpics/".$_FILES['uploadfile']['name']);
			   echo "<script>history.back();alert('File has been successfully uploaded!');</script>";
			   exit;
			 }
		}
  }
}

and HTML part is here:
...
<form id="ADupload" name="ADupload" method="post" action="ADupload.php">
...
<input name="uploadfile" type="file">
...
<input name="submit" type="submit" value="Upload" >
...
</form>

if you want to upload a file in a form, the form needs an ENCTYPE attribute set to "multipart/form-data" like so:

<form enctype="multipart/form-data" action="ADupload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadfile" type="file" /><br />
<input type="submit" value="Upload" />
</form>

thank you very much, it works. it displays the file has been successfully uploaded!, but i could not find file "test.fig" in the folder "ADpics". i use apache, php5 and mysql. the dir will be "C:\xampp\htdocs\mysite\ADpics".

also i want to change the name of uploaded file to a fix name as "fixname.fig", how can i do it in the first place without move and then rename uploaded file? any suggestions for doing that, pls?

cheers

the basic idea is that PHP takes the uploaded file and puts it into a temporary place with some temporary filename, tmp_name. this is the command that is supposed to move the file:

move_uploaded_file($_FILES['uploadfile']['tmp_name'],"/ADpics/".$_FILES['uploadfile']['name']);

try reading the docs on [man]move_uploaded_file[/man]. You'll see that the second argument determines what filename is to be used when you move the file. You should probably also check to see if there was an error moving the file:

move_uploaded_file($_FILES['uploadfile']['tmp_name'],"/ADpics/".$_FILES['uploadfile']['name'])
  or die('unable to move file')

In my site, I want to get a output in a XSL file. The data are retrieved from Mysql db. Retrieving the bulk records in a single file. When I access that download page simultaneously multi systems in the remote, I couldn’t get the file also my data are crashed. What is the problem? PHP.ini or DB? Plz tell me clearly. And how to solve this problem?

        Urgent. Thanks in advance.

thank you sneakyimp, you are right, the move function could not find such file
there are error messages:
"Warning: move_uploaded_file(/ADpics/test.gif) [function.move-uploaded-file]: failed to open stream: No such file or directory in C:\xampp\htdocs\mysite\ADupload.php on line 49"
"Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'C:\xampp\tmp\php27.tmp' to '/ADpics/test.gif' in C:\xampp\htdocs\mysite\ADupload.php on line 49
unable to move file"

the picture supposed to be uploaded to server, but i want to test it on my pc first, how can i do with "/ADpics/" to upload "test.gif" to appointed folder"C:\xampp\htdocs\mysite\ADpics".

thanks

Try reading and understanding the code.

thank you very much, i unserstood now. the default directory is under the current php file i executed, so i can simply place "ADpics/"before $_FILES function.

thank you again!!
